The threshold limit value (TLV) is a level of occupational exposure to a hazardous substance where it is believed that nearly all healthy workers can repeatedly experience at or below this level of exposure without adverse effects.

2021年9月30日 · Do you understand the difference between a permissible exposure limit (PEL) and a threshold limit value (TLV)? Both terms relate to the procedures that protect workers against the adverse effects of exposure to harmful substances.

Threshold Limit Values (TLVs ®) refer to airborne concentrations of chemical substances and represent conditions under which it is believed that nearly all workers may be repeatedly exposed, day after day, over a working lifetime, without adverse health effects.

2022年4月25日 · TLVs are the maximum average airborne concentration of a hazardous material to which healthy adult workers can be exposed during an 8-hour workday and 40-hour workweek—over a working lifetime—without experiencing significant adverse health effects. A TLV has three components:

What is the difference between a PEL, TLV and REL? The permissible exposure limit (PEL) is a legal limit in the United States for exposure of an employee to a chemical substance or physical agent. PELs are established by the Occupational Safety and Health Administration (OSHA).

2017年5月5日 · Threshold Limit Value (TLV) is a registered and reserved term of the American Conference of Governmental Industrial Hygienists (ACGIH). It is an occupational exposure value recommended by ACGIH to which it is believed nearly all workers can be exposed for lifetime without affecting health.

2024年5月15日 · TLV also known as the Threshold limit value of any chemical substance is a level of the chemical to which a worker can be exposed day after day for a working lifetime without any adverse effects.

2019年2月8日 · What Is Threshold Limit Value? Threshold Limit Values and Biological Exposure Indices are health-based values. TLVs are based on airborne concentrations of chemical substances.

2024年4月8日 · Time-weighted average threshold limit values (or TLV – TWAs), then, are measures of the average concentration of a hazardous substance that a worker can safely be exposed to over the course of a typical work week or workday.

TLV stands for Threshold Limit Value and is a term that is used to describe the level of a particular thing that a worker can be exposed to during their shift without experiencing any type of adverse effects.
